Web1. Abstract Circular cup drawing is the first forming process for forming the body of two-piece aluminum beverage cans / bottles. This paper has investigated optimum drawing process by changing circumferentially the blank holder forces, to draw earless circular cups from anisotropic blank sheet. At first, a drawing process analysis model has been made … Webanisotropy determines the average cup height of the extra deep draw. The planar anisotropy determines the extent of earring. For optimal drawability, a combination of a high 4 value and a low ΔR value is necessary [17]. Ears are formed at the flange of the cup using the deepest drawing possible [18]. Das et
Web“Earing” is a waviness in the top edge of a cup drawn from sheet metal. When a cup is drawn the top edge is noticed to naturally form an oscillating pattern. This results from anisotropy of the rolled sheet caused by the … The earing test is a test method applied in the metalworking industry and is used for the determination of sheet metal forming properties. The test is used to determine ear formation through punching followed by deep drawing of sheet metal blanks or strips into cylindrical, hollow formations. After drawing the cup, the earing tendency is ...
WebSep 18, 2024 · Earings appear easily during deep drawing of cylindrical parts owing to the anisotropic properties of materials. However, current methods cannot fully utilize the mechanical properties of material, and the number of earings obtained differ with the simulation methods.
